The Isaac Regional Council issued the updated warning as TC Debbie makes landfall between Ayr and Midge Point around midday today and edges closer to the region.

Isaac Local Disaster Management Group chair Anne Baker said people between Lucinda and St Lawrence, and inland including Moranbah, should immediately commence or continue preparations, especially securing boats and property.

Voluntary evacuation of people in low lying and coastal areas to a safer place is encouraged. Cr Baker advised residents to have emergency kits ready.
